Same thing that was in there.....cept they weren't painted the same as the vent like the original ones. http://www.pbase.com/dennygraham/image/161901522/originaldg

FYI The same bolts are used in the assembly of the original manifold mounted horns.

" original manifold mounted horn" not sure what that means | | | | | Joined: Jan 2013 Posts: 1,384 Shop Shark | | Shop Shark Joined: Jan 2013 Posts: 1,384 | There were 2 horn options in some of those years of production.
one manifold mounted horn that looks like a Klaxon.
The option or deluxe horn was two firewall mounted horns in the newer snail shell shape.
The Klaxon like horn is held together by 6 or 8 same bolts that assemble the hood vent. | | | | | Joined: Nov 2008 Posts: 465 'Bolter | | 'Bolter Joined: Nov 2008 Posts: 465 | I think I have the Klaxon, but it was mounted to the fender brace rods
I was wondering what that boss with 2 holes on the manifold was for | | |
